Stock up-mess up

Suji is magically pixelated out of his world while gaming and meets the goddess Seravene in a white space. Granted one wish, he chooses Stock, a private dashboard power that lets him spawn objects from his world by spending SP. He receives 1,000 welcome SP, unaware that 50 SP renews daily. In the wild plains, he later uses Stock to create a remote weapon and destroys a distant demon lord, only to discover he also killed the nearby hero party.
